[Kernel-packages] [Bug 1813620] Re: Xorg indefinitely hangs in kernelspace at least 2-3 times a day

2020-12-13 Thread QuCheng
I met same panic too, and enabled lockdep in kernel 4.19.67, the log is:

So it should be not release ww lock when exit, after parse, it's corresponding 
to ww_mutex_lock_slow_interruptible in ttm_eu_reserve_buffers. I review 
ttm_eu_reserve_buffers and qxl_release_reserve_list in the matser kernel 5.10, 
the function logic is still same, so I beleive this issue should still exist in 
kernel tip code.

Bug description:
  The graphical environment seems to hang when scrolling web pages in

  happened at least 5 times in the past 7 days. Happens in Kubuntu VM-s
  running under KVM and QEMU (3.1.0) on multiple host machines.

  This issue only started to happen sometime this month. First these
  VM-s were running 18.04 so I was hoping that updating them to 18.10
  would help, but it didn't. I'm guessing that some kernel update for
  both bionic and cosmic causes this.

  Since this bug causes the graphical environment to become totally
  unresponsive, this has already already cost me some lost data, but
  very fortunately not much.

[Kernel-packages] [Bug 1813620] Re: Xorg indefinitely hangs in kernelspace at least 2-3 times a day

2019-11-12 Thread Jaak Ristioja
I found that the latest drm-tip kernel for amd64 was at
https://kernel.ubuntu.com/~kernel-ppa/mainline/drm-tip/2019-11-08/ as
the more recent ones had failed to compile according to the READMEs.

The 2019-11-08 kernel (5.4.0-994-generic) boots fine, but after logging
in, running a GUI application and some clicks the screen goes black, and
the kernel logs this:

Title:
  Xorg indefinitely hangs in kernelspace at least 2-3 times a day

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  The graphical environment seems to hang when scrolling web pages in
  Firefox. Can't reliably reproduce during every scrolling, but it has
  happened at least 5 times in the past 7 days. Happens in Kubuntu VM-s
  running under KVM and QEMU (3.1.0) on multiple host machines.

  This issue only started to happen sometime this month. First these
  VM-s were running 18.04 so I was hoping that updating them to 18.10
  would help, but it didn't. I'm guessing that some kernel update for
  both bionic and cosmic causes this.

  Since this bug causes the graphical environment to become totally
  unresponsive, this has already already cost me some lost data, but
  very fortunately not much.

Sorry for the spam. I'm not used to those Ubuntu bug reporting tools.

I've been running 5.2.0-050200rc1-generic ever since the suggestion to
try the mainline RC. This bug did not re-occur until now. Here is a new
dmesg.

Title:
  Xorg indefinitely hangs in kernelspace at least 2-3 times a day

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  The graphical environment seems to hang when scrolling web pages in
  Firefox. Can't reliably reproduce during every scrolling, but it has
  happened at least 5 times in the past 7 days. Happens in Kubuntu VM-s
  running under KVM and QEMU (3.1.0) on multiple host machines.

  This issue only started to happen sometime this month. First these
  VM-s were running 18.04 so I was hoping that updating them to 18.10
  would help, but it didn't. I'm guessing that some kernel update for
  both bionic and cosmic causes this.

  Since this bug causes the graphical environment to become totally
  unresponsive, this has already already cost me some lost data, but
  very fortunately not much.

[Kernel-packages] [Bug 1813620] Re: Xorg indefinitely hangs in kernelspace at least 2-3 times a day

2019-05-02 Thread Kai-Heng Feng
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v5.1-rc7 kernel [0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed”, and attach dmesg.

Thanks in advance.
